Clever Ways to Use Plant Ash for Controlling Flower Pests and Diseases

Plant ash not only supplies flowers with nutrients such as potassium, but also has a fairly good effect on preventing and controlling flower pests and diseases.

1. Controlling leaf blight: Take 1 kg each of plant ash, tea seed cake and sulfur powder, and 1.5 kg of lime, crush them into powder and mix evenly, then scatter 1.5 to 2.5 grams per pot on flowers prone to leaf blight.

2. Controlling leaf spot: Mix 3 kg of plant ash with 1 kg of quicklime powder evenly and apply by scattering, 40 to 60 grams per pot, or sift and dust the powder, or simply scatter plant ash alone.

3. Controlling root rot: Plant ash has a very good control effect on flower root rot. The specific method is to first dig away the soil around the roots and clear away the soil around the decayed roots. Scrape off the diseased root bark, apply 0.5 to 1 kg of plant ash per plant to cover the roots, then cover with soil.

4. Controlling powdery mildew: For flowers affected by powdery mildew, dig away the root soil to a depth of 5 to 10 cm at a distance of 5 to 10 cm from the main stem, cover each plant with 0.5 to 3 kg of plant ash, and add a thin layer of soil on top of the ash.

5. Controlling seedling-stage diseases: Flower nursery beds are prone to damping-off, anthracnose and other diseases at the seedling stage. When humidity is high and temperature is low, seedling diseases occur severely and often cause large numbers of seedling deaths. Plant ash can be scattered along the furrows at 20 to 25 kg per mu.

6. Controlling aphids: Grind plant ash into powder and sift it, then dust the plant ash onto the aphid bodies in the early morning before the dew has dried (or sprinkle water first). You can also put the ash in gauze and shake it out, repeating once every three to five days for 2 to 3 consecutive applications.

7. Controlling root maggots: When root maggots harm flowers at the seedling stage, using pesticide as a root drench can easily cause phytotoxicity, so 30 to 40 kg of plant ash can be applied per mu in the seedling bed. The application method is to evenly scatter plant ash on the bed surface at the seedling stage, then hoe and turn it evenly so the ash and soil are fully mixed. You can also apply plant ash in the furrows before sowing or planting, and then sow or plant.

8. Controlling underground pests: When raising seedlings, bulbous flower seedling beds are often harmed by underground pests such as white grubs. Using plant ash as a base fertilizer for control, or covering seed bulbs with plant ash, can significantly reduce the damage.
